0.1mm Precision Automatic Grasping, SingTown Technology Empowers New Scenarios in Electronic Assembly

In the automated production lines of electronic assembly manufacturers, the feeding and placement of bulk SOP chips have always been one of the critical precision processes. Due to the random arrangement of chips, varying orientations and angles on both sides, manual identification suffers from high error rates and slow speeds, affecting placement accuracy. Manufacturers aim to utilize SingTown Technology's OpenMV smart camera, employing embedded vision algorithms to quickly identify the position, angle, orientation, and Pin1 marker of SOP chips, and feed the data back to robotic arms for automated grasping and placement. The identification area is approximately 200×200mm, within a distance of 200mm, primarily targeting SOP14/SOP16 chip types. The system must operate stably under complex lighting conditions, achieve millisecond-level identification feedback, and meet the dual requirements of real-time performance and high precision, providing an intelligent visual identification solution for electronic production lines.

Electronic assembly manufacturers have achieved significant results in the automatic identification and positioning of bulk SOP chips by utilizing SingTown Technology's OpenMV smart camera.

The system employs an OpenMV intelligent camera installed above the material tray to capture real-time chip images. Its edge-side AI utilizes machine vision algorithms to perform contour detection, morphological analysis, and orientation determination for SOP chips.

First, the image preprocessing module performs denoising and edge enhancement, segmenting overlapping or rotated chips. Subsequently, the deep learning model, combined with template matching methods, enables rapid identification of chip models. Finally, the coordinate extraction module transmits the precise X and Y positions as well as orientation information of each chip to the robotic arm, achieving automated grasping and placement.

The operational results indicate that the OpenMV intelligent camera solution achieves over 99% recognition accuracy in high-density bulk material scenarios, with single-chip positioning precision reaching the 0.1mm level, significantly enhancing assembly line efficiency and stability.

By introducing SingTown's intelligent cameras, manufacturers have not only achieved automated identification and precise positioning of bulk SOP chips through edge deployment but have also effectively reduced labor costs and defect rates, providing a reliable and intelligent upgrade path for electronic assembly production.
